A similar behavior is observed in the Portuguese gas system: the level of LNG
regasification noticeably increases with variations of VIP Iberico. An example of this
can be seen in figure 7.3 below, where a significant increase of LNG regasification
levels occurred during the month of October and December of 2016, enhanced by
the decrease of VIP Iberico during the same period. Carriço underground storage in
Portugal helps with daily modulation especially on higher demand days.
In France, there is higher modulation of the demand over the year linked to the
heating for residential consumers (seasonal effect). From a general point of view, the
regasification and pipeline entries are mainly stables over the time, and the variability
of the demand is assured by the UGS which fully play their role.
As shown in the graph, the higher period of demand in the beginning of 2017 as
been managed through a higher solicitation of the UGS, the LNG stocks in the
terminals being at a low level at that time.
